Function interrupts::eoi

pub fn eoi(irq: InterruptNumber)

Send an end of interrupt signal, notifying the interrupt chip that the given interrupt request irq has been serviced.

This function supports all types of interrupt chips – APIC, x2apic, PIC – and will perform the correct EOI operation based on which chip is currently active.

The irq argument is only used if the legacy PIC chip is active on this system; newer APIC chips do not use this.
